The recipe for Fever Tonic can be found in the Surgeon's Workshop within Trosky Castle. You have two options to access this workshop. The first option is to sneak into the workshop discreetly. The second involves using your persuasive skills to convince the chamberlain that you can help with his stomach issues by making him a digestive potion, which grants you entry to the workshop.

If you prefer not to sneak, you can progress through "For Whom the Bell Tolls" by delivering the horseshoe. After that, return to the forge and speak with Cook Fanka. Offer to help her with her locked chest, and she'll lead you to the noble's kitchen. Upon entering, you'll notice the chamberlain suffering from stomach pain. Engage him in conversation about his health and pass the skill checks to gain access to the Surgeon's Workshop. If you craft both the digestive potion and the Fever Tonic, the chamberlain will introduce you to Thomas.

Should your skill checks fail, you'll need to steal some food and exit the kitchen. Head to the other side of the courtyard, where you'll find stairs leading to a door on your right. This leads to another kitchen where a guard is present. Hand over the stolen food to the guard to make him leave. Then, you can sneak upstairs to the Surgeon's Workshop. Locate the physician's journal on the bookshelf, read it, and use the station in the room to brew your potions.

The herbs required for the Fever Tonic are already set up at the surgeon's station. Simply open your book to the page for Fever Tonicum and follow these steps:

• Pour wine into the cauldron.
• Add 3 handfuls of Feverfew.
• Lower the cauldron and boil for 2 turns of the sandglass.
• Grind a handful of Elderberry Leaves using the mortar and pestle.
• Add the ground Elderberry Leaves.
• Add 2 handfuls of Ginger.
• Retrieve a phial from the bottom left shelf of the station, under the wine.
• Distill the tonic using the Still.

If you don't succeed on your first attempt, don't worry. You have ample herbs to work with, and there are more in the chest within the room. Given your prior experience with potion-making, crafting the Fever Tonic should not pose a significant challenge.

Once you have the Fever Tonic, your next step is to reach Thomas. If you've gained the chamberlain's trust by crafting the digestive potion, return to him with both potions. Otherwise, use the noble's kitchen to sneak up to the chapel where you'll find Thomas and his sister, Adele. Speak with Adele to complete the quest.
